Fi and ET **** Fi and ET are displayed after one breath and have a continuously updated
breath average.
The following method is used to calculate end-tidal (ET) values:

The highest concentration of CO
weight function applied to favor values closer to the end of the cycle.
ET will typically decrease below nominal value (ET
